Didnt pass Smog test

I replaced my battery recently and then took my coupe to get a Smog test done for the California DMV. It didnt pass. Everything was good except for the Secondary Air Sestem. They said that since I replaced the battery that it needs to be driven for a while to allow the car to achieve its drive cycle. I drove it for 175 miles. Freeway, city, traffic.... does anyone know what I need to do or how long does it take to achieve a drive cycle?

Thanks for helping

Dan

Assuming you did some normal driving including getting a highway, perhaps you actually have a problem with your air injection system. Do you have a CEL? If so, did you clear it? Can you hear it running when you do a cold start?

Warm it up

Mine didn't pass once.. I didn't warm it up enough. Take it out and make sure it is nice and HOT.... Try again.

Get a code reader and check it yourself before you go. There should be no codes and all monitors should be ready, and 0 incomplete. It can take some time to get 8 complete monitors. If you clear the system you may have to start over.

FWIW on my GranTurismo I followed the instruction from Maserati service (and other wise web tips) to clear the Secondary Air System status after my (used) car was delivered: drive about 500 miles. It did the trick. I checked the status using an OBD reader and my iPhone every day for about 2 weeks, and it eventually turned to Ready
So I was able to pass smog check (in Northern California) yesterday.

The system has to go through a few warm up cycles from completed cold start(1-4?).

Will net set with just one long drive with a couple start stops.

Smog Test

This may well very by jurisdiction but my experience in Atlanta is that the tester can make a difference.

I had bad luck with both my Maserati and my Toyota Sienna with the testing shop that relied only on the OBDII computer test. It was frustrating with repeated attempts, a trip to the Toyota dealer, drive cycles and more. This included my own pre-testing of the cars with my code reader showing all sensors ready and no faults. The OBDII only testing shop actually was unable to report the details of the fault. They would only report that the car did not pass.

Eventually the OBDII only shop referred me up the street to a testing shop that actually tested the emissions with a probe inserted in the tail pipe. This shop has been able to pass my vehicles without problem so far.

I do not know the situation in California, but here in Atlanta not all shops are the same.

Yes, it must be driven, the amount of miles varies depending on your distance from leaving that God forsaken state.

dc8333 - Try a can of BG 44K - drive 10 miles then test. My wife's BMW went from 3 fails to pass after adding a can of this injector fuel cleaner. My longtime BMW mechanic recommended it...said all the good mechanics use it. Good luck.

BG is decent stuff, but I don't see how that helps a car run the monitors so it can pass an OBD2 test.? Injector cleaner would only help in that case if the car was a 95 or older as the emissions are done on a dyno most of the time with a sniffer in the tailpipe...Jason

Monitors don't all run independently. If there's actually a problem and one won't set to ready, it can prevent other tests from initiating.
